Modelagem de dados mCSEM 3D usando computação paralela

We develop the numerical modeling of marine controlled-source electromagnetic (mCSEM) data in three-dimensional models of hydrocarbon exploration using parallel computation. The models have as reference three stratified layers, formed by the air, the sea and the sediment host with a thin threedimensional reservoir buried. We show the parallelism of the mCSEM 3D data in a multitransmitting survey, where for each transmitter position we have a different forward model. For this, we use MPI library and the client server approach. We observe that when the width and the length of this reservoir are in the same magnitude order, the in-line responses are very similar and the three-dimensional effect is not detected. In turn, when the difference in the sizes of the width and<br>the length of the reservoir is great, the effect 3D is detected in in-line measures of the biggest dimension of the reservoir.
